Abstract

Aligned with the European Circular Economy (CE) action plan, the construction industry strives for a sustainable and circular future. Industrial Symbiosis practices foster the emergence of circular construction ecosystems where waste outputs from demolition projects are considered as resource inputs for one or more construction projects. Such a process connecting heterogeneous projects symbiotically is known as waste-to-resource matchmaking. It is challenging to ensure efficient matchmaking due to quantity, quality, and spatial-temporal uncertainties embedded in construction and demolition projects. The development of methods to identify, coordinate, and evaluate symbiotic matchmaking remains an open issue in the built environment. This research proposes an agent-based simulation model to analyse how individual matchmaking leads to systematic CE performance from a complex adaptive system perspective. A conceptual model framework based on the concept of shearing layers is used to instantiate a simulation model demonstrating matchmaking dynamics over time and space. The results indicate that waste transfer hubs could provide extra storage time and allow larger transportation distances, which potentially contribute to successful matchmaking. In future research, the model’s applicability and validity will be illustrated through real-life urban mining cases.
